Summary Report
Species Richness
Percentage of all species observed network-wide that have been observed in this polygon
Biodiversity Rarity
Species Rarity measures the richness of species weighted by how rare they are.
Values indicate the polygon's species rarity rank expressed as a percentile, with 100% being the polygon with the most rare species.
Biodiversity Uniqueness
Biodiversity Uniqueness measures the distinctiveness of the ecological community in this polygon compared with all others.
Values range from 100% for communities completely distinct from all others to 0% for communities identical to all others.
Biodiversity Irreplaceability
Biodiversity Irreplaceability measures how key this polygon is - compared with all others - to ensure that all species across the network are sufficiently protected.
Values indicate the polygon's irreplaceability rank expressed as a percentile, with 100% being the most and 0% the least important.
Ecological Community Change
Ecological Community Change measures the percentage change in ecological community composition and evenness from year to year.
Negative values indicate less change between years than the average background rate.
